Hi, Sorry, but I've to call again... The developers seems very willing to include a realtime kernel there repo. They need some people who wants to build and maintain it. This is really a chance for linux audio, especially on Debian. *This is the moment!* So please consider to offer your help in building, maintaining and/or testing!
